When entering long keywords into the search box it seems impossible to enter a second or third to narrow down the search, since the first entry remains highlighted and one cannot place the cursor either side of it to continue.
My question therefore is, can one elongate the search box to facilitate this?
You can just continue typing, when you hit the right border of the search field. The text can be longer than the size of the search field.
But I would use teethe filter to refine the search. The keywords you add to the Quick Group will appear in the Showing filter and you can check off the additional search terms there. For example:
I have been searching for the combination of Sunset and Lighthouse.
